I had just walked into the kitchen while on the phone..A large flat ufo was flying over some houses across the street and i could see the size. it was much larger than the houses with about 20 feet of air space between it and the homes. i had looked out my kitchen window while closing my blinds. it had just gotten dark outside but the ufo was much darker than the sky. .I was facing south when i saw this black triangle ufo flying overhead. it was pretty low and going at a stead speed. only took about 3 minutes before it changed direction and disappeared behind a hill and some trees. i could see it very clear. it was black and very flat. lights were randomly flashing. not very large lights and flashing slowly. there were a few airplane's higher up in the sky they were flying se and traveling at a familiar speed and height. the ufo was flying south and then turned to go east. i was pretty shocked. i mentioned it to the person i was talking to on the phone and hung up to try to get a picture or video of it. i am not sure the video turned out but i will check. i didn't have much time before it was out of my sight.
